First, we open it. Wow, it's pretty! Then we arrive on the chord diagrams page and we say to ourselves... Cool, these are real gypsy chords! There are even diagrams in base 5. And then we jump on a first grid and... Mr. Watremez, you're going to have to explain something to me... So many promises only to finally display beginner chords that will never sound gypsy... What's the point??? All the chord harmonization work has to be redone... For the themes, it's the same thing... Everything has been simplified so that beginners can find their way. Basically, if you follow this book; it's flat, it's sad and it certainly doesn't sound gypsy. Incomprehensible
